There are not too many flash units for the new Sony DSLR's that do not cost a fortune, you have in this price segment much of a choice. The workmanship is rather moderate, but the device is working as it should. There is the device - as far as I can remember - Equivalent by other companies, well then, is a China - OEM. I had it. At an Alpha SLT35 Nice small, light and perfectly adequate for normal use. The tilt reflector allows bounce, also important. Otherwise, I can only comment of the "Wolf" Only connect. Good lightning at excellent price.
